This invention relates to e rocess and machine for hitting full fashioned stockings, and more particularly to the manufacture of both the leg and foot of such a socking on. s. singlestrai ht knitting machine.

@ne of the ohgects of e invention is to proride s more periect stockin then has heretoiore been ohteined when 'ttiog the entire stocking on one machine.

lit has heretofore been known to melts on entire fuii ieshioned stocking on e, singie straight knitting machine by knitting the heel ceps or tohs without pressing ofi the stitches on the instep needles. 'lo ovoid press-ed? on the insteg} needles it has heretofore been suggested y 3i381ii18 such the U. S. psteotto Gebers 0. 1,534,311, deted April 21,1925, that the needle her be divided in three portions, the middie portion corresponding to the instep, and that this portion of the needle her he withdrew trim the line of knitting iostrumentolities ot the beginning of the heel so that e pressed ceiinot ecciir. Use disadvantage, of this *1 arrangement, however, is that there is denger of the is iio 'hwomieg punctured and cm: by the imoclnng-over hits or sznlrers In of this ithes heeri stiggested that the needle her he divided into ortions end that the middle ortion thereovhe ivoteiiy mo'snted so t at the n es he moved out etthe r. c f t 9 sifikem ondirnocHng-over hits during the knitting oi the heei. During the first part of the of the heel, however, the fabric {of the heel cops is not long enough to permit 1 the instep portion of the need e bar. to remain clear of the knocking-over bits and sinkers end durin part of the knitting cycle it lies between t esinkers and knockingover bits, with the result that the loops thereon are easily torn ordamsged.

According to applicants invention the disadvantages of the methods described above are ell avoided by the process and .machine which will now beset forth and which involves the use of both the divided needle her and a divided Presser her. An example of a, patent showing at divided presser her is the U. S. Patent to Nobel No. 1,033,723, dated July 23, 1912. According to this invention the melting of the heel is carried out in two steps. During the first step the press-0d of the instep needles is prevented either by leevin the instep needles in the knitting line on using mechanism such as e divided presser her or byinsteganeedies e very slight disportion of the needle her. During the first in which the lmitted courses are held in douhied or folded form the stitches on the instep needles are not appreciably e'nier ed and the stitches are not in s. position to N demeged by the sinkers or knocking over hits. When e suiiicient number of seems have been Emit to permit the swim ing army of the instep portion of the need? her beyond and clear of the mm c of the imoolfing-over bits end sinkers, t e instep rtioii is swung sway end the remainder oi the heel caps knit with the fsbricflield out stro' ht.

Referring to Figures 1 end 2 of the drawing, the sinker head icontsins the resser her 2 whose mid portion is sdapte to' be 'heel caps A, B, E, F and C, D, G, H are begun and knit in the doubled or folded form with the fold lying between the sinkers 3 and the knockin -over bits 4. After, say, twenty or twentyve courses have been knit the pivotal mid-portion of the needle .bar 5 is swung out to the right of the dotted position 5' carrying the needles beyond the reach of the sinkers 3 and the knocking- ,over bits 4. Thereafter the knitting of the heel caps is completed, the pivotal middle portion of the needle bar gradually swingin further out until it reaches the position 5 'When the heel caps are completed the pivotal middle section can be moved back to its 7 starting position and the foot can be knit on the instep' portion of the heel caps in the usual manner.

In Figure 3 I have shown the preferred embodiment of my invention, namely, the machine in which instead of using a divided presser bar the instep portion 6 of. the needle bar is swung a short distance out of the knitting line during the first steplof the process,'in which position 7 it is clear of the presser bar and yet does not bring its stitches far enough out to be hurt by the sinkers or knocking-over bits.' After twenty or twenty-five courses have been knit, as in the previously described embodiment of my invention, the second step of the knitting is carried out in a manner similar to that of the first process, namely, theinstep portion of the needle bar is swung out until the needles are beyond the range and clear of the sinkers and knocking-over bits and the fabric is held out in a straight line by the instep needles.

What I claim is:

1. In a process for knitting a full; fashioned stocking, the steps of knitting a lubits and knitting the remainder of the heel caps.

3. In a process for knitting a full fashioned stocking, the steps of knitting the leg on a straight line of needles, knitting a lurality of courses to constitute part of the eel caps in direct succession to the le while simultaneously preventing press-oil on the instep needles by moving the latter beyond the range of the presser bar but not out of the range of the sinkers and knocking-over hits, the fabric thus knit bein held in doubled-over form, then pivotin t e instep needles out of the knitting line yond the range of the sinkers and knocking-over bits until the heel cap fabric thus far knit is strai htened out, knitting the remainder of the eel 4 simultaneously preventing press-off on the instep needles without removal of the instep needles from the knitting line, the fabric thus knit being held in doubled-over form, then pivoting the instep needles out of the knitting line beyond the range of the sinkers and knocking-over bits until the heel cap fabric thus far knit is straightened out, knitting the remainder of the heel caps while maintalning the fabric straightened out and then returning the instep needles to the knittin line to knit the foot.

n testimony whereof I have signed my name to this specification.
